4. Programming
Programming is setting a LSN detector to the desired operating mode.
Programming is carried out with the >WinPara< software using a PC or laptop connected
to the fire panel.
All sensor signals are analyzed continually by the internal evaluation electronics and
are linked with each other via an inbuilt microprocessor.
The detectors OTC 410 LSN OC 410 LSN and OT 400 E LSN are programmed by
specifying the operation location (e.g. computer room, office, large kitchen).
The selection of the operation location determines the optimal characteristic diagram
for fire and disturbance variable evaluation.
With low sensitivity of the optical sensor in the OTC 410 LSN, the detector only triggers
if smoke and also an increase of the CO concentration or the temperature is detected.
With the types OTC 410 LSN and OT 400 E LSN, the operating mode can be changed.
That is, individual sensors can be switched off:
-- Switch to optical (sensitivity O unit = low, T unit = switched off)
-- Switchover to thermo--differential (sensitivity T unit = A2R, O unit = switched off)
-- Switchover to thermo--maximum (sensitivity T unit = A2S, O unit = switched off)
With purely optical detectors O 400 E LSN, the sensitivity of the optical sensors can
be set on 3 levels. Depending on the operation location, the optical sensor in the
detector is thus adjusted to the environmental conditions.
For fire recognition, the optical detector uses the temporal behavior of the fire variables
that deviates significantly from the temporal behavior of disturbance variables and
also from the time behavior of a detector test with aerosol. Depending on the sensitivity
set, therefore there are also different trigger times when testing with a test aerosol,
outside of maintenance operation (10s to max 60s).
The thermal detector T 400 E LSN is programmed by taking into account the ambient
temperature and installation height with the selection of the sensitivity class.
Programming of the optical, thermal, and chemical detector and the linking of all detectors
via algorithms significantly increases the detection ability and security against false alarms.
